STEPHEN J. POPLAWSKI, OF RACINE, WISCONSIN, ASSIGNOR 0F ONE-HALF TO STUART M. HARIBRIDGE, OF RACINE, WISCONSIN.

COUPON-SHEARS.

Application filed December 20, 1917.

To all whom it may concern:

Be it known that I, STEPHEN J. PoPLAw- SKI, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Coupon-Shears; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to devices used primarily for detaching coupons from bonds, and more particularly to a pair of shears for this purpose.

The object of the invention is to provide a pair of shears having angular blades for detaching two sides of the coupons at one operation and to insure proper engagement of the lateral ends of the blades.

With the foregoing in view, the invention resides in the novel construction herein described and claimed and shown in the accompanying drawing wherein:

Figure 1 is a side elevation;

Fig. 2 is an enlarged edge view;

Fig. 3 is a perspective view of the pivot bolt: and

Fig. 4 is an enlarged section through the pivot.

In the drawing above brieflv described, the numerals 1 designate the two blades pivoted together at their rear ends by a bolt 2 and having their front ends directed laterally at right angles as seen at 3, said blades having coacting cutting edges in front of the pivot and handles 4 in rear thereof.

The bolt 2 passes through alined openings 5 in the blades 1 and the axes of the two halves 6 and 7 of said bolt are offset laterally so that turning of said bolt will slide the blades longitudinally in respect to each ther to cause proper cutting engagement of the lateral ends 3. The head 8 of be". 2 is preferably formed with a screw driver kerf 9 and with an outstanding annular flange 10 contacting with one blade, flange 10 being engaged by a screw 11 which is threaded in said blade and holds the bolt against rotation after adjustment. The other end of the bolt may be equipped with the usual nut 12.

In use, the blades 1 sever the coupons Specification of Letters Patent.

Patented Nov. 26, 1918.

Serial No. 208,095.

from the bonds on two sides at a single cut and whenever necessary, the bolt 2 is loosened and turned slightly to force the cutting edges of the lateral ends 3 into proper relation for effective cutting.

Since probably the best results are obtained from the exact construction shown and described, this construction is preferably used, but within the scope of the invention as claimed, minor changes may well be made should occasion so dictate.

I claim:

1. A pair of shears comprising a pair of handles, a pair of crossed blades extending downwardly from said handles, in substantial alinement therewith, said blades having coacting cutting edges and having their front ends extended laterally and also provided with cutting edges, and a combined pivot and eccentric connecting said blades for sliding them longitudinally with respect to each other to insure proper cutting engagement of said lateral ends, the axes of said combined pivot and eccentric being parallel with said lateral ends.

2. A pair of shears comprising a pair of handles, a pair of crossed blades extending forwardly from said handles, in substantial alinement therewith, the front ends of said blades being extended laterally and the crossed rear ends of said blades having alined openings, both the longitudinal and lateral portions of the two blades having coacting cutting edges, a bolt passing through the aforesaid openings and having the axes of its two halves offset laterally and positioned parallel with said lateral ends of said blades, whereby turning of said bolt will slide said blades longitudinally with respect to each other to insure proper cutting engagement of said lateral ends, a nut threaded on the free end of the bolt, a lateral flange on the head of said bolt, and a screw engaging said flange and threaded into one of said blades to hold the bolt against rotation.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

STEPHEN J. POPLAWSKI.
